Ultra-compact body (74 * 30 * 18.8 mm) that easily fits into a wallet, chest pocket or MP3 case and can be adsorbed onto iron-containing surfaces for flexible placement. Supports TF card expansion from 4-128GB (card not included) to store extensive recordings and music. Uses advanced DSP intelligent noise reduction to cut ambient noise by more than 90%, paired with an omnidirectional stereo microphone that captures distant and low-volume sounds in clearer stereo HD.
